Fix Bug #507: [住院护士站-住院记账-补费] 项目单位未获取、执行科室显示内码且缺乏默认/模糊搜索逻辑

1. 修复单位字段默认为空：selectChange中增加defaultUnitCode逻辑，优先取minUnitCode，回退到unitCode
2. 修复执行科室显示内码：统一positionId和el-option value为字符串类型，避免类型不匹配导致el-select无法匹配选项
3. 科室匹配增加String类型转换：find时用String(d.id)===String(patientOrgId)避免因类型不同找不到匹配科室
4. loadDepartmentOptions和getDiseaseInitLoc增加.catch优雅降级，避免API失败时页面阻断
